Abstract

The invention discloses an anti-ageing and waterproof chloroprene rubber material. The anti-ageing and waterproof chloroprene rubber material is prepared from the following raw materials in parts by weight: 40 to 80 parts of chloroprene rubber, 30 to 50 parts of methylvinyl silicone rubber, 45 to 55 parts of calcium hydroxide, 4 to 10 parts of feldspar, 2 to 8 parts of ceramic microsphere, 20 to 40 parts of modified straw fiber, 2 to 6 parts of glass micro-bead, 0.2 to 0.6 part of a titanate coupling agent TTOPP-38, 0.5 to 1.2 parts of ethyltrimethoxysilane, 0.2 to 0.6 part of sulfur, 2 to 4 parts of tert-butyl phenol formaldehyde resin, 1 to 2 parts of titanium acetylacetonate, 2 to 4 parts of an ultraviolet absorbent UV-531, 0.5 to 1.5 parts of trimethyl phosphate and 1 to 2 parts of epoxy soybean oil. The anti-ageing and waterproof chloroprene rubber material provided by the invention has excellent waterproof, tough and sealing properties, excellent anti-ageing performance, good anti-impact performance and high rigidity.

Description

technical field [0001] The invention relates to the technical field of rubber, in particular to an aging-resistant and waterproof neoprene rubber material. Background technique [0002] Neoprene is widely used, such as making conveyor belts and transmission belts, covering materials for wires and cables, making oil-resistant hoses, gaskets, and chemical-resistant equipment linings. The disadvantages of chloroprene rubber are poor water resistance, poor toughness, and aging resistance that cannot meet the demand, which needs to be solved urgently. Contents of the invention [0003] Based on the technical problems in the background technology, the present invention proposes an aging-resistant and waterproof neoprene material, which has excellent waterproof, toughness and sealing performance, excellent aging resistance, good impact resistance and high hardness. [0004] A kind of anti-aging waterproof neoprene material proposed by the present invention, its raw material comp...
